The National Weather Service warned that the early-week rainfall plus recent mild temperatures could displace ongoing ice jams and lead to the formation of new jams.

Typically, ice jam flooding is localized, but residents near rivers and creeks prone to them should monitor conditions closely.

The ice jam situation in the Northeast was set into motion by persistently cold temperatures from late December into January that led to a rapid freeze of rivers, creeks and lakes. When milder temperatures and rain move into these frozen locations, the ice can break up and become clogged in river or creek bends or against obstructions, such as bridges.

As a result, a water rise occurs and sometimes floods locations upstream from the jam. When the jam breaks up, flooding can occur in downstream locations.

Here is look at some of the ice jams we've seen over the past week or so in the Northeast.
